DOOR Fou sTovEs, RANeEs, AND FURNACES.

SPECIFICATEON forming part of Letters Patent No. 306,7327 dated October2l, 1884.

Application tiled December 22, 1882. (Bo model.)

o all whom, it may concer/1,:

Be it known that I, WILLIAM G. Fiscnnn, of the city of Cincinnati, inthe county of Hamilton and State of Ohio, have invented certainnewanduseful Improvements in Doors for Stoves, Ranges, and Furnaces, ofwhich the following is a specification.

My invention relates in general to the construction of the door and theframe which receives it.

My invention is alike applicable to stoves, ranges, or furnaces.

The various features of my invention and the advantages resulting`therefrom will be apparent from the following` description.

Heretofore hinged fire-doors carrying cheeks have been combined with astove to serve as a chute or leader for conducting the fuel into thefire-box of the stove or other cooking or heating apparatus; but toinsure a perfect performance of their proposed functions theconstruction of these cheeks and the combination of the door-cheeks andstove have been such as to either compel the formation and presence ofsupplemental cheeks projecting from the stove, or the door-cheeks had tobe constructed to pass into the fire-chamber or stove.

One feature of my invention enables me to dispense with the use ofsupplemental cheeks, and also avoid the necessity of having the cheeksenter the fire-chamber or stove.

The preferred forms of stop mechanism which I employ in conjunction withmy said door-cheeks, to prevent the door from dropping too far whenopened, enable me to dispense with separate plates or, lugs heretoforeattached tothe frame to form stop mechanism.

Iteferring to the drawings forming part of this specification, Figure 1is a front elevation of a door and frame illustrating my invention, thedoor beingelosed. Fig. 2 is a side elevation of the same, the edge ofthe frame being broken away, as indicated bythe dotted lines Yy 3/ ofFig. l. Fig. 3 is a side elevation showingthe door opened, the edge ofthe frame being broken away, as in Fig. 2. Fig. 4 is a sectionalel'evation showing the door open, the section being taken at the dottedlines a; x ofFig. l, and in a plane at right angles tothe front surfaceof the door. Fig. 5 represents a vertical section through the door-shelfand stove front plate, illustrating a certain modification of myinvention to be hereinafter specified.

Fig. '6 represents a side elevation of a doorcheek and stove frontplate, illustrating a modification of the stove mechanism for preventingthe door when opened from falling down too far, and which modificationwill be here- 6c inafter fully described.

In the present instance I have shown my invention as constructed forapplication to a range, but from the following description it,

will be obvious that it may be as readily applied to stoves or furnaces.

A is the door-frame, which is to be secured to the side of therange;'and this frame is provided with the fuel-opening A. At thebottoni of this opening A is an extension 7o projecting shelf, B, which,in connection with the door, serves asa chute for the fuel; and thisshelf is preferably cast with the frame A. The door is secured to theframe or its extension by any suitable hinge-connection.

A preferred hinge-connection is as follows: The shelf B is provided ator near each end with the hingeplates B, cast with or -otherwise securedto the shelf or to the lower part of the frame A, and preferably locatedon the 8o under side of said shelf. Each of these plates B has an end,b, which retains the door, whether opened or closed, and while beingopened or closed in position with relation to the shelf.

When the shelf B is of sufiicientstrength, this 8 5' ings b are usuallypresent in the door to reeeive the end of the hooks (see Fig. 4) whenthe door is open.

To the plate d is preferably secured a liningplate, E, asliglitair-space being left between said plate and lining, and the lower edgeof roo this lining covers the ends ofhooks b, not permitting any dust orashes tointerfere with the hinges, and this plate is usually perforatedwith a series of small openings near its lower edge, and the plate d islikewise perforated with a series of perforations, j', near its upperedge. Any dirt or ashes which may enter the holes at the bottom of thelining E is prevented The lower edge 9o frominterlering withthehingesbylugs orstuds l door C, hinged at or near the outer edge ol'j, (indicated by dotted lines in Fig. 1,) to

which studs the lining E is riveted. The purpose of this airspacebetween the plates and the air-openings is to keep the door-plates fromwarping and to furnish heated air to improve combustion. The cheeks Dextend below the hinges of the door (when the door is closed) a distanceequal to the distance from the hinges to the face ofthe frame A, as'shown at c, and these extensions are shaped in or nearly in the are of acircle the center oi" which is formed by the hinges ofthe door, theperiphery ofthe circle being at the face of the frame A, so that as thedoor C is turned on its hinges the edge of this extension c is at alltimes close to this frame, and these cheeks D, with the extensions c,i'orm the sides ot' the chute, the bottom ol' which chute is formed bythe door when open and the shell" B. A suitable stop or stops forholding the door, after being opened, in posi tion whereby it shall forma part of the chuteway are present at any convenient and desirablepoint.

A desirable inode ot' applying such a stop or stops is shown in thedrawings, and is as follows: lhe lower end ot' each ot' the extensionstIis provided with alug or stop, e, which, when the door is opened, entersa stop-hole, u, in the frame A, preventing the door from dropping beyonda certain point. lnstead ot' these holes a, projecting lugs may betermed on the tace ofthe l'rame, against which the lugs c may strike, asillustrated in Fig. Sheet 2, but this lastnlentioned construction isobviously not so desirable as the construction herein previouslydescribed.

As beforeintimated, the ends may be eyes or hooks. I prefer to constructthem in the shape ot' hooks, i'or the reason that thus the door may bereadily lil'ted from the hinges at any time, and this capability isobviously a great advantage.

rlhe amount ot' projection ol" the shelfl D may be increased ordiminished to suit the particuA lar class of work to which the door isto be applied, the width of the cheeks D andthe extension c beinggoverned by the amount oi' projection ol' the shell'.

rllhe door is usually provided with a` suitable handle or extension, s,for convenience in opening or closing the door.

fhen employed l'or stoves, the shelt'B will usually be cast with theside ofthe stove.

p Having thus f'lescribed my invention,what I claim as new, and desireto secure by Letters Patent, is as follows:

l. ln combination, the frame having shelf D, and the door (j, hinged tothe shelf and provided with cheeks having extensions c, whose peripheryis formed in the arcol a circle whose center is the hinge, saidperiphery being in close proximity to the l'ront surface ot' the frameand outside ot' the door-opening of the frame, substantially as and forthev purposes speeilied.

il. ln combination, the frame, shelf, and

the shelf, and provided with. cheeks having extensions e, whoseperiphery is of the form of an arc concentric with the hinge, and inclose proximity tothe front surface of the frame and outside of thedoor-opening of the frame, the extensions being provided with lugs e',adapted to engage suitable stops for checking the descent ot" the door,substantially as and l'or the purposes speciled.

3. rlhe combination oi'thedoorC, frame,and shelf, and suitable stopmechanism for arresting the descent ot' the door, and the cheeksconnected to the door and having extensions c formed in the are ofacircle whose periphery is concentric with the hinge-connection ot' thedoor, substantially as and i'or the purposes specified. p

4t. The frame A, provided with projecting shelf lll, in combination withthe door C, provided with cheeks D, having extensions e, said door beingdetaehably hinged to the outer edge ot' the shelf' for enabling the doorto be .readily lifted o'tl', said extensions being formed in the are ofa circle the center ol" which is the hinge7 the periphery at all timescoming into close proximity to the frame, and pro' vided with a suitablestop for preventing the door from opening beyond a certain point,substantially as and for the purposes spccilied.

5. ,lhe frame supporting the shelt', provid ed with the hinge-plates B,carrying hooked extremities b, in combination with door j, having cheeksl), with extensions c, shaped and operating as described, and suitablestop mechanism for arresting the descent of the door, su stantially asand l'or the purposes specified.

(5. The frame A, provided withshell having secured thereto thehinge-plates B', said plates being provided with hooked extremiities l),in combination with the door C, provided with cheeks l), havingextensions e, shaped as described, and provided with lugs c for engagingwith the holes e, said door be` ing hinged to the hooked extremities I)bycylindrical ridges d, substantially as and foi-the purposes speeilied.

T. The combination ol'the frame, shell', and plates D', having hookedextremities b, and the door provided with rod d' and slots I1' l'or thereception ot` saidV hooked ends, subslantially as and for the purposesspecified.

S. The frame A, having stop-holcs a., in combination with the door C,hinged to the .trame and provided with side cheeks, 1'), havingextensions e, said 'extensions being provided with lugs e', adapted toengage with the holes a in the frame, the lugs c' and the holes a, beingin the same plane with the extensions c, substantially as and 'for thepurposes specified.
